He pays $900 per month in rent for the home and $300 per year in property and liability insurance. The owner of the house wants to sell it, and Alex is considering making an offer. The owner wants $160,000 for the property, but Alex thinks he could get the house for $150,000 and use his $25,000 in 3 percent certificates of deposit that are ready to mature for the down payment. Alex has talked to his banker and could get a 5 percent mortgage loan for 25 years to finance the remainder of the purchase price. The banker advised Alex that he would reduce his debt principal by $1,700 during the first year of the loan. Property taxes on the house are $1,400 per year.
